Jennifer wasn't able to join due to work commitments, but I found a copilot to go with and share the flying. I did the first leg to KBFI (Boeing Field International) which was an easy 5H leg with nice weather.

Since we were there already, we went to visit the Boeing Museum of Flight at KBFI. It's actually one of the best flight museums I've seen so far: a full visit takes over 4H and even a quick one takes over 2H :)

The next morning, weather was bad, so we just drove to KPAE to visit the Boeing Museum. Unfortunately, we were not allowed to take any pictures of the factory floor. This is too bad since it was pretty cool to see 787s and 747s being built from scratch on huge floors.
We were able to take pictures of the static displays and planes seen from the outside though:

Weather still wasn't great, but it was VFR in Boeing field and Friday Harbour, so we figured we'd be able to link the two somehow. It wasn't a very straight line, but we ended up doing a safe, albeit a bit silly considering, VFR on top flight where we climbed over 10,000ft to clear the clouds and leave the cloud area around Seattle. An other flight was able to get there between layers but I didn't find such a path and just didn't wan tot be scud runnings with no so flat land around.

cool shadow of our plane in the clouds with a rainbow around it. Neat!

As predicted by my skypad with XM weather, weather got a worse as we were about to enter California and got closer to Mt Shasta. We had to make a sharp westbound turn and fly around it to stay VFR on top (I had no interest in getting under the cloud layer and being sandwiched between it, and the rising terrain, or ending up in a box canyon).

while in our way, the cloud made a nice wave, like surfing inside a crashing wave (this was just as we turned west)

we then got some nice VFR on top all the way back

and by Oakland, we got under the forming overcast that was starting to cover the bay (incidently, not Palo Alto yet)
